MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 267,955, dated November 21, 1882.

Application filed October 19,1882. (No model.)

To all whom it may concern Be it known that I, ALBIN WARTH, a citizen ofthe United States,residin g at Stapleton, in the county of Richmond and State of New York, have invented new and useful Improvemen ts in Mechanical Movements, of which the following is a specification.

- This invention relates to an improvement on the mechanical movement which is described in Letters Patent No. 151,457, granted to me May 26, 1874, and which consists essentially of a carriage which is acted on bya traveling belt, and provided with a head containing a tubular swivelstandard, and a shaft from which motion is transmitted to-a drill,cutter, grinding-disk, or'other tool, so that the carriage, together with the tool, can be moved backward and forward, and the tool can be swung in either direction without throwing its rnriving-shaft out of gear with the traveling be t.

a The improvements which form the subjectmatter of my present invention are pointed out in the following specification, and illustrated in the accompanying drawings, in which- Figure 1 represents a side view. Fig. 2 is a transverse vertical'section in the plane y 51 Fig. 1. Fig. 3 is a plan or top view. Fig. 4 is a sectional plan or top view of a portion of the-mechanism on a larger scale than the previous figures, the line at at, Fig. 5, indicating the plane of section. Fig. 5 is a side view of the same. The remaining figures are details, which will be referred to as the description progresses.

. Similar letters indicate corresponding parts.

In the drawings, the letterA designates the traveling belt, and O is the carriage. The, traveling belt extends beneath a pulley, a, which is mounted on a shaft, a, Fig. 1, to which motion is imparted by any suitable means.- From the pulley a the traveling belt passes over a pulley, a Figs. 1 and 3, thence over a series of tables, B B B B (four being shown in the drawings,) to a pulley, a thence down beneath a pulley, a, Fig. l, and up over a pulley, a thence back over the tables B B B B to a pulley, a, and finally back to the pulley a. The tables B B are connected by a joist, b, secured to the inner edges of the tops of said tables; and in the same manner the tables B B are connected bya joist, b. These pulleys a a are. loosely mounted on a shaft,

0. which is firmly secured in a bracket, a secured on the opposite end of the rail 0. This rail is situated in an open space between the joists b b, and it is supported by brackets 6 secured to the joist b, and on it rest the wheels 0 c of the carriage O. From this carriage extends a hanger, 0 provided with two wheels, 0 0 which are mounted on vertical axles and bear on the opposite sides of the bottom rail, 0 (see Fig. 4,) so as to keep the carriage steady. From the carriage rises a fixed spindle, 0 on which is loosely mounted a pulley, c and to the pulley is firmly secured a second pulley, c".

" Beneath the pulley 0 is situated an arm, 0

which swivels on the spindle c and which carries two tightening-rollers, 0 By turning this swivel-arm in an oblique position (see Figs. 3 and 4) the two strands of the traveling belt A are brought to bear firmly from opposite sides upon the pulley 0 so that a revolving motion is imparted to the same and to the pulley 0". Suitable mechanism (not shown in the drawings) serves to lock the swivel-arm in the required position.

a From the brackets a a extend arms a, Figs. 1, 3, and 4, which form the bearings for vertical spindles, on which are loosely mounted pulleys d, round which extends a belt, D. By

causing this belt to engage with a hook, at, formed on the side of the carriage 0, (see Figs. 4 and 5,) said carriage can be readily moved over the entire length of the tables B B simply by turning one of the pulleys d or by pulling on the belt D in the required direction. This operation can he performed without disturbing the men at work on thedifferent tables, While if the belt D is not there the man who wants to move the carriage from one table to another has to walk along on the edges of the tables, and the men at work there are interrupted. When the carriage has reached the required place the beltD is unhooked.

0n the spindle o of the carriage O is fitted a swivel-cap, E, which is supported bya screw, 6, the point of which engages with a cavity in .the bearing for the pivot f of a double-armed lever, F, which is provided with sockets f f at its ends, and one arm of which is curved so as to pass round the cap. In the socket f is secured a rod,f on which is placed an adjustable weight,f The socket f supports a r0d,f to the outer end of which is firmly secured a frame, G, that forms the bearings for two shafts,g g, and the support for the head H, which carries the tool to which motion is to be imparted. I

On the shaft g, Fig. 4, is firmly mounted a pulley, g and on the shaftg, which extends at right angles to the shaft g, is feathered a friction-wheel, g and firmly mounted a pulley, g, which connects by a belt, 9 with the pulley c on the carriage O. The outer end of the shaft 9 has its bearing in a block, 9 which swivels on a vertical pivot, g Fig. 5, and from which extends a lever, 9 which is exposed to the action of a spring, 9 The inner end of the shaft 9 has its bearing in a bracket, g Fig. 6, secured to the frame G, and provided with a slot, which permits the end of the shaft 9 to slide toward and from the pulley g on the shaft 9. When the lever g is permitted to follow the action of the spring g the frictionwheel g is pressed up against the flat side of the pulley g and if the shaft g is turned its motion is transmitted to the shaft g. When the lever g is drawn out against the action of its spring 9 the friction-wheel g is thrown out of contact with the pulley 9 In this position the lever 9 can be locked by a latch. The friction-wheel 9 can be moved in the direction of the axis of its shaft by means of a hell-crank lever, 9 which is retained in the required position by a serrated bar, 9 Fig. 7. The object of this movement is to adjust the speed of the motion transmitted to the shaft g. The motion of the traveling belt A being supposed to beuniform,the speed of the motion imparted to the shaft 9 by the belt g will also be uniform; but by moving the friction-wheel g toward the shaft g the speed of the motion imparted by this shaft will beincreased, andvice versa. It will be seen from the above description that such adjustment of the speed can be effected without regard to the position which the frame G assumes in regard to the traveling belt A, and without interrupting the motion of this belt.

In the example shown in the drawings the head H carries a knife for cutting cloth or other materials, and it is provided with a foot-plate, h, which formsthe supportfor the material near the place where it is to be cut. Beneath this foot-plate is a roller, h, which is grooved to fit the rail 0, Fig. 8, or any other rail provided for this purpose, so that when the roller is placed upon such rail and the belt D is manipulated the carriage 0, together with the head H, can be moved readily over the tables B B B B without disturbing the work which may be distributed over said tables or the workmen engaged on such work. The head H may, however, be constructed to carry a drill, a grindin g-disk, or any other tool, and the roller It may be connected to some portion of the frame G. The weightf is so adjusted that it balances the frame G and head H, or nearly so, and that the operation of adjusting the head on the rail 0 or on any part of the tables is facilitated. Another advantage of this balance-weight isthat the workman is thereby enabled to adjust and govern the action of certain tools upon the work. For instance, if the head contains a disk for grinding off the surfaces of piano-tops, it is essential that the pressure of the grinding-disks upon the work shall be adjusted with the greatest nicety, while at the same time the tool must be so arranged that it can be freely moved over the work in any direction.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore described, of the carriage U, the traveling belt A, acting on a pulley mounted on the carriage, the rail supporting said carriage, the

head H, connected to said carriage, a tool which receives motion from the pulley in the carriage, the table or tables on which the carriage travels, and the belt D, for moving the carriage, together with the head H, over the tables.

2. The combination, substantially as hereinbefore described, of the carriage O, the traveling belt A, acting on a pulley mounted on the carriage, the rail supporting said carriage, the

head H, carrying a tool which receives motion from the pulley in the carriage, and the frame G, which swings on a pivot, f, connected to the carriage, and forms the connection between said carriage and the head.

3. The combination, substantially as hereinbefore described, of the carriage O, the travel-' ing belt A, acting on a pulley mounted on the carriage, the rail supporting said carriage, the

head H, carrying a tool which receives motion' from the pulley in the carriage, the frame G, which forms the connection between the head H and the carriage, the belt D, and the guideroller h.

4.
